Pentax F 4,5 - 5,6 100-300 focusing problem

Hi all!

I'm new to this forum and have a question to all Pentax experts here.
I have a K-7 and bought a used Pentax F 4,5-5,6 100-300mm lens. The problem is that when i go above 135mm it can't get focus beyond approx 10 meters. I have tried with both AF and MF. How can this be? And is it an easy fix? Please advise.

Best Regards
